Sad to say, the Conservative record on a living wage in London is not as proud as Mr Cameron likes to make out. In 2007 Brian Coleman, since appointed as Chair of the capital’s Fire Authority by Boris, vocally opposed introducing the LLW for cleaners, branding a proposal to do so as “just ridiculous”.

For balance, because I hadn’t really intended to comment on the general election, it’s fair to point out that since coming to power Boris has shown a pretty progressive face of Conservatism including by continuing his predecessor’s support for the LLW and (after a bit of a wobble) expanding the range of fare discounts for the less well off and other deserving groups. All very good calls and much welcome.
